Hi all, I think this comes down to confusion between deploying SEP through SWD or deploying it through the SEP integration component. I've tried it with the aplicability rules as suggested and it does what I want (chooses 32 or 64 bit) but the install actually fails, it seems because I'm trying to use the packages that were created through SEPIC.
According to this article, http://www.symantec.com/business/support/index?page=content&id=HOWTO60858 the only official way to deploy SEP is through SEPIC, which creates a task rather that using SWD. If I go this route, I have to have two tasks, one for 32 and one for 64 bit, so back to the original problem!
Should I just go for using SWD instead?
